Description

[Detailed description of the invention] [Industrial application field] This invention relates to a seeding machine used for agricultural work.

[Prior Art] Conventional negative pressure seeding machines are pulled by a tractor or the like, and cannot be moved by hand.

[Problems that the invention aims to solve] Conventional negative pressure seeding machines have a power source and a vacuum pump mounted on a cultivator or the like that is pulled by a tractor, and the vacuum pump performs negative pressure sowing via two flexible tubes. It was connected to the machine's negative pressure port and positive pressure port. A negative pressure seeding machine was used while being towed by a tractor.

However, if it is towed by a tractor, etc., the negative pressure seeding machine cannot be used unless the person has a tractor or the like.

If you are trying to eliminate the need for a tractor or the like, you can consider moving it manually, but if you try to move it manually, the problem becomes where to place the power source and vacuum pump. For example, if a power source and a vacuum pump are mounted on a negative pressure seeding machine, the negative pressure seeding machine becomes heavy and difficult to push around.

Therefore, by suspending a combination of a power source such as an engine and a vacuum pump from the human body like a brush cutter, and connecting the vacuum pump and the main body of the negative pressure seeding device with a hose, it is possible to create a negative pressure seeding device without increasing the weight of the negative pressure seeding device. It becomes possible to easily push the pressure seeding machine. This invention is intended to enable the power source and the main body of the negative pressure seeding device to be easily and quickly connected and disconnected in such a manual negative pressure seeding machine.

[Means for solving problems] This will be explained with reference to the drawings.

The base end of the paddle tool 2 is pivotably mounted on both sides of the vehicle frame 1 to which the negative pressure seeding device main body 5 is attached, and is configured to be fixed and released at any inclination angle, and can be attached and removed at any location on the paddle tool 2. One of the fluid pipe connectors 4a, 4b is attached, and one of the removable fluid pipe connectors 4a, 4 is attached.
b and the negative pressure seeding device main body 5 by two flexible tubes 6a,
6b, and the other of the removable fluid pipe connectors 11a and 11b is attached to each tip of the negative pressure hose 9a and the positive pressure hose 9b, which are connected to the combination body 8 of a power source such as an engine carried on the human body and a vacuum pump. The above-mentioned removable fluid pipe connector is constructed so that one and the other can be connected and disconnected.

[Example] The explanation will be based on the drawings.

1 is a car frame, 12 is a front wheel attached to the front part of the car frame 1, 13 is a rear wheel attached to the rear part of the car frame 1, 5 is a negative pressure seeding device main body, 14 is a seeding guide tube, and 2 is a U-shaped paddle tool. , its front lower end is pivoted 3 to the vehicle frame 1. 15 is a horizontal member attached to the middle of the paddle tool 2, 4
a and 4b are one side of the concave-convex fitting type removable fluid pipe connectors fixed to the horizontal member 15, and 6a and 6b are one side of the concave-convex fitting type removable fluid pipe connectors 4a and 4b and the negative pressure seeding device main body 5. It is a flexible tube that connects the The negative pressure seeding machine is configured as described above.

8 is a combination of a power source (engine, etc.) and a vacuum pump that is carried on the human body by hanging from the shoulder or waist, 16a and 16b are the negative pressure port and positive pressure port of the vacuum pump, and the negative pressure hose 9a and positive pressure hose 9b
The other hoses 9a, 9b are connected to each other, and the other removable fluid pipe connectors 11a, 11b are attached to the tips of both hoses 9a, 9b. The other of the removable fluid pipe connectors 11a, 11b is configured to be easily and quickly disconnectable from one of the above-mentioned removable fluid pipe connectors 4a, 4b.

In addition, the figure shows that the concave type of the recessed and recessed fluid pipe connector is attached to the flexible tubes 4a and 4b, and the convex type of the recessed and recessed type removable fluid pipe connector is attached to the hoses 9a and 9b. However, there is no problem even if the opposite is true.

[Function] The vacuum pump carried on the human body and the negative pressure seeding device main body 5 are connected by the removable fluid pipe connectors 4a, 4b, 1 with uneven surfaces.
1a and 11b so that they can be functionally connected. Also, the two can be separated arbitrarily.

[Effects of the invention] According to the invention, the vacuum pump 8 using a motor is attached to the human body, which makes the negative pressure seeding machine independent and lightweight compared to conventional systems that use the power source of other power drives. This has advantages such as the ability to easily and quickly connect the negative pressure seeding machine and the vacuum pump using the detachable fluid pipe connector.
